Troubleshooting
This information will help you troubleshoot issues related to the Cellular 500W.
The following table describes possible issues and provides suggested actions to resolve the
issue.
Issue Action
Cannot program the Cellular 500W. Check the programming device and software version. Program Cellular
500W using an approved handheld computer running Field Deployment
Manager (FDM) 4.4 or higher.
Cannot read the Cellular 500W. A Cellular 500W that is not programmed does not transmit a SCM+.
Reprogram the Cellular 500W and perform a reread. If a Cellular 500W is
not initially programmed, it does not bubble up and listen for an SCM+.
The Cellular 500W is reporting an
invalid read.
A Cellular 500W that has set the Register Error flag causes an Invalid
Read to display in the FDM Consumption field.
Marginal readability due to the
Cellular 500W location (for
example, a Cellular 500W deep
inside a pit).
Consider reprogramming the Cellular 500W for Hard-to-Read Mode. This
increases the output to high power levels
Note: This mode reduces battery life.
The handheld programmer is
locked up and button presses
produce no response.
Soft boot the handheld. Reference the documentation for your
programmer.
